RB25DET Conversion and Wiring
Nice project offered up to us to rewire the engine bay in this Silvia to suit the engine upgrade and the new LINK ECU. We’re starting with the LINK “A” and “B” engine Looms, customising them to suit the engine Install and sensor locations. All New Bosch Sensors have been used for Fuel Pressure, Oil Pressure, Intake Air Temp, which will now be looked after by the LINK G4+fitted in the OEM Location. We’re fabricating our own custom coil loom to suit the Bosch Audi Coils and incorporating the brand new NZEFI Injector Harness. A Franklin Engineering Cam Angle Sensor kit replaces the stock Nissan CAS for more accurate Ignition Timing Control. Stock Style plugs are being used where possible with Deutsch Connectors taking up duties everywhere else. The Whole loom will be protected by Loom Braid.
Boost is provided by a Garret GT35/82R and a 50mm TurboSmart External Wastegate keeps Boost levels in check. Intake Temps are kept in check with an Aeroflow Performance Front Mounted Intercooler.
Below: A big job ahead, initial work. Coil Loom coming together, Earth and Power Cables Waiting for Terminals. Main Harness gets its final Loom Wrapping before Braid goes on and Final Fitment in place. Battery relocation to boot is on the cards too for this Street and Track Weapon. The LINK ecu has been mounted neatly in the factory location, adding to the OEM nature of the install.
Some work on the underside of the car also required, speed sensors, earth cable etc, as well as the beginnings of the battery relocation. We’ve supplied a lightweight, very compact battery for running the vehicle. Looks are deceiving, this wee beast offers a pulse crank of 600A, more than enough to wake the big six cylinder up, even on the coldest mornings! Large diameter Ground and Power cables ensure minimal voltage drop for rapid cranking and less strain on the alternator.
